in p>1644, in the first month of the seventeenth year of Chongzhen in Ming dynasty, Li Zicheng, the conqueror, formally established the Dashun regime in Chang 'an, with the title of Yongchang. Later, he led a large army to cross the river and crusade eastward, killing Beijing, the capital of the Ming Dynasty.
At the beginning of March, Li Zicheng arrived at the gate of Xuanfu (Xuanhua, Zhangjiakou City, Hebei Province), and the capital was in danger. In desperation, Chongzhen named Wu Sangui Pingxibo and ordered him to give up the checkpoint and enter the customs. At this time, Wu Sangui was the company commander of Liaodong, stationed in Shanhaiguan. Wu Sangui received an order from the diligent king to send troops into Shanhaiguan. When he arrived in Fengrun, Hebei Province (now Tangshan City, Hebei Province) not far from Shanhaiguan, he heard the bad news, the capital fell, and Chongzhen hanged himself, so he led his troops back to Shanhaiguan.
in early April, Wu Sangui personally led his men to Beijing to meet the new emperor Li Zicheng. But on the way, I heard that Dashun army arrested a large number of high-ranking officials in Beijing, and their father Wu Xiang was among them. What excites him even more is that his beloved concubine Chen Yuanyuan has also been robbed. According to legend, Wu Sangui flew into a rage at that time and shouted sharply, "A gentleman can't protect a woman, so how can he see people?" Immediately, he returned to Shanhaiguan for the second time, surrendered and rebelled, and staged a unique scene of "rushing to the crown and being angry as a beauty", which made a great contribution to the Qing court's determination of the Central Plains.
